A hollow metal pipe of internal diameter 7cm and external diameter 8cm is 6.16m long calculate the volume of metal making the pipe in cubic centimetres​

The volume of the hollow metal pipe is approximately 72.571 cubic centimeters.

Step-by-step explanation:

The volume of the metal is the space occupied by the hollow pipe. Since it is a hollow cylinder, the volume (), in cubic centimetres, is defined by following expression:

(1)

Where:

- External and internal diameters, in centimetres.

- Length, in centimetres.

If we know that , and , then the volume of the hollow metal pipe is:

The volume of the hollow metal pipe is approximately 72.571 cubic centimeters.

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
